A decarboxylative protocol has been developed toward a range of carbocycles. The key success is based on the use of a batch of newly designed cyclic carbonates as substrates that can provide carbon-carbon zwitterion intermediate under palladium catalysis.

Furfurylidenemalononitriles and thienylidenemalononitriles were treated with 1,3-cyclohexanediones to afford 2-amino-4-hetaryl-5-oxo-5,6,7,8-tetrahydro- 4H-chromene-3-carbonitrile derivatives. The molluscicidal activity of these compounds was investigated.
Cinchona alkaloid and di-: Tert -butyldicarbonate-DMAP promoted efficient synthesis of (E)-nitroolefins

The synthesis of nitroolefins from aldehydes and olefins is generally limited by the formation of a mixture of cis and trans compounds. Here we report an alternative, metal-free protocol for the synthesis of β-nitroolefins from arylidinemalononitrile using cinchona alkaloid along with di-tert-butyldicarbonate-DMAP in high yields with total selectivity.
